New biomarkers in acute cardiac care

In conjunction with clinical assessment and the ECG, simple and rapid blood tests have become the standard for the detection of myocardial infarction. Starting in the year 2000, recommendations by the European Society of Cardiology and other major cardiology societies worldwide have begun to state uniformly that a rise in cardiac troponins - sensitive and specific markers for dying cells in the heart - is a prerequisite for the clinical diagnosis of myocardial infarction.

Issues on cholesterol: diet, statins and genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

Endoscopic ultrasound 99.1 percent accurate in diagnosing pancreatic neoplasms

Researchers from St. Louis University School of Medicine in Missouri report that EUS and EUS-FNA is 99.1 percent accurate in diagnosing pancreatic neoplasms (abnormal growths or tumors) in patients who were referred for endoscopic ultrasound (EUS) because of CT and/or MRI reports of two common, though somewhat ambiguous findings - enlargement of head of pancreas (HOP) or dilation of the pancreatic duct (PD).

FDA clears non-invasive test to help manage heart transplant patients

The U.S. Food and Drug Administration has announced it has cleared for marketing a non-invasive test that uses molecular expression techniques to assist doctors in managing heart transplant patients post-surgery for potential organ rejection.

Time is right to make cancer control a development priority

For public health, the complexity of cancer control has increased enormously following the shift of the disease burden from wealthy to less affluent countries. Cancer causes around 7.9 million deaths worldwide each year. Of these deaths, more than 72% are now occurring in low- and middle-income countries. This is a shocking statistic, with huge implications for human suffering, health systems, health budgets, and the drive to reduce poverty.

Stanford Medical School severely restricts industry funding of continuing education for physicians

The Stanford University School of Medicine will no longer accept support from pharmaceutical or device companies for specific programs in continuing medical education, as industry-directed funding may compromise the integrity of these education programs for practicing physicians, officials said.

Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

Media coverage of persistent vegetative state and end-of-life decision-making

In 1990, Theresa Schiavo, an American citizen, had a cardiac arrest that caused irreversible brain damage which led to a persistent vegetative state diagnosis. A few years later, this diagnosis became a source of conflict over the interruption of artificial nutrition.
